[Contracts] No lightweight loan-status view; get_loan triggers accrual and per-id calls are required

Why this matters

loan_manager/src/lib.rs exposes get_loan, get_borrower_loans, and get_total_loans, but no view to list loans by status or fetch a lightweight status without triggering accrual via get_loan. Off-chain indexers and the frontend must call get_loan per id. A simple get_loan_status(loan_id) -> LoanStatus and/or pending-loans accessor would reduce calls and avoid the accrual side effect.

Acceptance criteria

• Add a lightweight get_loan_status(loan_id) view returning the stored LoanStatus without running accrual
• Optionally add a paginated accessor for a borrower's loans filtered by status
• Add tests for the new view(s)
• Document the new view(s) in the contract README section

Files to touch

• loan_manager/src/lib.rs

Out of scope

• Global loan enumeration across all borrowers
• Indexer infrastructure

I'd like to work on this issue.

I'll add a lightweight get_loan_status view that returns the stored loan status without triggering accrual logic, making it more efficient for frontends and indexers. If the contract structure supports it cleanly, I'll also add a status-filtered borrower loan accessor with pagination to reduce the need for multiple contract calls.

I'll include tests covering the new view functionality and update the contract documentation so integrators can easily adopt the new access patterns.
